Document processing devices are often employed in networked systems in business and academic sites providing users the option of sending a given print job to one of several devices for processing. Organizations employing multiple document processing devices desire options for financing and tracking printer utilization, and may prefer to pay for print services and related devices and materials based on usage rather than paying up front for equipment and consumable accessories. Moreover, manufacturers and resellers of document processing devices desire the ability to provide such account options to end-users. The conventional office equipment use model has been for the end customer to acquire document processing devices along with associated consumables, either on a paid-up or leased model. A leased model may include provisions that allow the customer to be billed on a periodic basis for use of the equipment and consumable supplies, with the charges including lease payments for the equipment as well as charges for use of consumables. The act of returning spent toner cartridges and other replaced consumables requires extra effort by the user that often prevents them from supporting return requests and sponsored recycle, reclaim programs. Accordingly, there is a need for improved methods and systems for managing document processing device consumable usage and implementing consumable replacement return programs for document processing devices.

BRIEF DESCRIPTION

Account manager systems and methods are disclosed for managing prepaid consumable return refund programs in which automated or semiautomatic refunds are provided to customers who return spent consumable products used in document processing devices by crediting customer accounts and/or by applying print units directly to document processing devices. While conventional return/refund programs tended to suffer from limited customer participation, the presently disclosed techniques initiate refunds by automatic addition of credits to the customer account, and in certain cases, to also perform direct application of print units to the specific document processing device from which a returned consumable product came, and thus can provide an effective incentive for customer compliance beyond that possible in conventional programs.

In accordance with certain aspects of the disclosure, methods and account management systems are provided for managing prepaid consumable return refund programs in which account information is stored including an available credits value indicating an amount of account credits currently available to a customer account, and an association is determined of a consumable with a particular customer account. The method further includes automatically adding credits to the particular customer account and adding a corresponding number of new credits to the available credits value for the particular account for a full or partial return refund associated with the consumable. The account crediting in certain embodiments may be done (in whole or in part) when or after the customer installs a replacement consumable and/or when the replaced consumable is returned, and the customer may be provided with an automatic notification of the addition of account credits. In certain embodiments, moreover, the account information further includes current pricing information for converting account credits to print units for specific document processing devices, and print units are automatically applied to the particular document processing device for the full or partial return refund associated with the returned/replaced consumable, with or without automatic notification of the print unit application, either when a replacement consumable is installed or when a returned consumable is received. In other embodiments, print units are directly applied to a specific document processing device without intervening addition or conversion of account credits.

The determination of association between a returned consumable and a specific document processing device is done in some embodiments based in whole or in part on the stored account information. In certain embodiments, the account information includes device subaccounts individually associated with a particular document processing device with device identity information as well as consumable identity information, where the association for initiating the return refund actions is determined at least partially based on the document processing device and consumable identities in the account information. In certain embodiments, for example, the consumable identity may be received in a message from a particular document processing device for updating the account information, such as where the document processing device reads a serial number from an electronic memory in the consumable. In some embodiments, the device subaccount information includes document processing device identity information as well as information indicating the number of print units used by the particular document processing device, in which the association of the consumable with the particular document processing device is determined at least partially based on the total print units used information of the account information. In other embodiments, document processing device identity information is obtained from the consumable after the consumable is returned, such as by reading an electronic memory on the consumable that was written by the document processing device in one implementation. In some embodiments, a consumable level is monitored for a particular document processing device, and when it is determined that the device needs or will soon need a replacement consumable, the system causes a replacement consumable to be shipped to the customer for the particular document processing device. In some implementations, the customer may be automatically notified at the time of replacement shipment, and the automatic account crediting/print unit application can be performed then as well in some embodiments. Moreover, the addition of account credits and/or application of print units can be partitioned in certain embodiments, for instance, with a partial refund being initiated when a replacement is shipped or installed, and with a remainder being refunded when the spent consumable is received at a return center.

DETAILED DESCRIPTION

Referring now to the drawings, FIG. 1 shows a networked commercial environment 2 with one or more networks 10 interconnecting a server 100 with one or more resellers 200 and customers 300, where access to an account manager system 104 implemented in the server 100 is accomplished via a portal 102. The server 100 can include a single computer processor or multiple processing elements, and the server 100 may be implemented as a single integrated processor-based structure including memory or may be implemented in distributed fashion including multiple structures, some of which are processor-equipped. The account manager system 104 can be any suitable combination of processor-based hardware, logic, processor-executed software, firmware, or combinations thereof, and may be implemented in a unitary platform (e.g., server 100) or in distributed fashion across multiple processor-equipped devices. In the embodiments, the reseller(s) 200 and customer(s) 300 include reseller and customer networks, respectively, with computers at the reseller(s) 300 and customer(s) 300 being equipped with agent software programs (e.g., customer agents 360 in FIG. 1) operative to allow authorized, secure, encrypted communication between authorized reseller/customer personnel and the account manager system 104 through access via the portal 102. Moreover, the customer agents 360 provide for operation and management tasks between customer document processing devices 320 registered to a customer account and the account management system 104 via the portal 102, and also allow customer to use the agent 360 to communicate with one or more processing devices 320 coupled to a customer network 302. The customer network 302 may include any form of electronic communication network(s) by which the devices 320 can communicate directly or indirectly with the customer computers 330 and/or with the account manager system 104, including without limitation dedicated networks, internet connections, and may include connection of one or more devices 320 with the account manager system 104 via telephony networks (wired and/or wireless or combinations thereof). Thus, the network connection of the devices 320 includes situations in which a primary network connection is inoperative (“network down” condition) with recovery or alternative communications means (e.g., telephone line connection to the devices 320) being provided as an alternative for communication between the devices 320 and the account manager system 104 for validation or other steps.

Referring also to FIG. 2, an exemplary distributed customer computing environment is illustrated, including two exemplary logical device groups 310 a and 310 b, each including one or more computing devices 330, some of which are equipped with agent components 360. In the illustrated environment, the computers 330 are selectively authorized to print or initiate other document processing operations via the devices 320 or predefined subsets of the devices 320, for example, by appropriate password entry & verification via the customer's network 302 and associated network elements and/or by access/usage control features implemented in the devices 320 themselves. The individual groups 310 also include one or more document processing devices 320. The illustrated customer computers 330 and device 320 are operatively coupled via a customer network 302 which may be any suitable form of communications network or interoperative networks. In addition, one or more print servers 50 are coupled with the network 302, where certain portions of the network 302 may be interconnected by cabling or one or more portions may be wireless, and where one or more exemplary computers 330 d and 330 e are illustrated in FIG. 2 with operative communicative coupling to the network 302 being implemented using a wireless network transceiver interface component 340. Any number of user computers may be operatively coupled to the network 302, including without limitation desktop computers 330 a and 330 b, laptop computers 330 d and 330 e, and any number of document processing devices 320 may be coupled with the network 302. Different forms of document processing devices 320 are networked together in this example to provide the user computers 330 with a broad range of document processing options available for a given print job or other task. One or more of the devices 320, moreover, are registered to one or more customer accounts and are operable via the network 302 or by users actuating on-board controls (e.g., buttons, keypads, etc.) for copying and scanning operations and other tasks. The document processing devices 320 may include one or more managed consumables 322 (FIG. 1 and FIG. 4 below) such as non-print media items or materials consumed by the device during document processing operations, including without limitation toner, ink, a replaceable fuser module/component, replaceable imaging units, waste toner bins, transfer belt, or the like.

The exemplary document processing devices 320 shown in FIG. 2 include relatively low throughput externally fed color as well as black and white desktop printers 320 a and 320 b, respectively, intermediate speed drawer fed color and black and white printers 320 c-320 e, high volume color as well as black and white printer/scanner/copier (i.e., multi-function) devices 320 f-320 h, a desktop combination printer/scanner/copier 320 i and a combination printer and facsimile machine 320 j. Document processing devices 320 may include any device operable to perform one or more document processing functions, including without limitation printers, scanners, copiers, combination scanner-printer-copier machines, and the like. In FIGS. 1 and 2, the customer network 302 and the external network 10 can be arranged in any suitable configuration for example star, ring, bus, tree, mesh, etc. or combinations thereof, and may be a wired network, a wireless network, or combinations thereof, wherein the illustrated customer network 302 of FIG. 2 provides one or more wireless nodes 340 for connectivity for portable laptop computers 330 d and 330 e through various WiFi or other wireless means.

The devices 320, moreover, are configured to allow normal customer/user initiated operation based on available print units applied to the device 320 in accordance with a customer account administered via the account manager system 104, and may optionally be authorized by the account particulars to perform at some low level of functionality even when the applied print units are depleted as discussed further below. By this device functionality, all or at least certain aspects of the actual or expected cost of document processing operation of a given device can be attributed to the customer based on usage, including the initial device cost, cost of consumables 322, costs for servicing (e.g., repairing, troubleshooting, etc.), costs for access to customer support, and other associated costs, rather than being paid up front by the customer.

Referring now to FIGS. 1 and 3, usage of the devices 320 is managed via these prepaid accounts by the system 104 using various account information 110 stored in a data store operatively coupled with the server 100, where the data store can be external or internal to the server 100 or combinations of internal and external storage. The account information 110 is stored for a plurality of accounts, for example, a first account for management of prepaid devices 320 of the first device group 310 a in FIG. 2 and a second account for devices 320 of the second group 310 b, and account information is also stored for multiple different customers, including those customers or ‘vendors’ that register so-called ‘public’ devices 320 as discussed further below in connection with FIG. 11.

As best shown in FIG. 3, the account information 110 for individual accounts includes general account information 111 a (e.g., account owner name, address, billing information, authorized users, etc.), a credits used value 111 b, for instance, indicating the number of credits that have been previously applied to devices 320 to date from account inception, or in a given predefined period (e.g., year-to-date, etc.), and an available credits value 111 c indicating an amount of account credit units currently available to the account for which the corresponding customer has previously paid and which can be applied to one or more devices 320 by customer-initiated request. The available credits information 111 c in certain embodiments includes two or more values indicating credits available for different departments or organizational entities within a given customer enterprise. The account information 110 in this embodiment also includes credit transfer information 111 d and reduced functionality permission information 111 e (described further below in connection with FIG. 3).

The account information 110 for a given account also includes current pricing information 112 including at least one conversion factor for converting account credits available to the account to print units for specific document processing devices 320 registered to the account. The current pricing information 112 for individual accounts in this embodiment includes device type pricing information 112 a including at least one price factor 112 a 1 for each specific document processing device type for converting account credits to print units, and at least one print unit price modifier 112 a 2 for each of a plurality of different specific document processing device types for increasing the print unit price if a given customer account provides for including one or more additional cost factors for consumables, service, and support in the print unit price. The pricing information 112 also provides customer specific pricing information 112 b including discount information 112 b 1 and modifier flags 112 b 2 indicating applicability of one or more of the print unit price modifiers 112 a 2 for the given customer account.

In some embodiments, different discount information 112 b 1 can be provisioned in the account information 110 for specified document processing devices 320 obtained by a given customer from different resellers 200 and/or for specified document processing devices 320 obtained in different locations or regions, thereby providing reseller flexibility in offering discount incentives to select customers on a global or locality basis. Program provisions can be associated with specific account numbers prior to a reseller offering the accounts for sale to end-customers 300, for example, where the account particulars include account pricing (conversion rates for converting credits into print units), print unit valuation equivalent to typical print images based on coverage, color content, etc., inclusions of service, supplies and media, various incentives, etc. The pre-established account particulars can be associated with a device 320 upon account initiation prior to delivery to the customer 300. In addition, promotional incentives like time frame duration and/or number of printed images can be managed in concert with product usage information associated with and tracked by a customer account, for instance, by tracking use debits and credit balance payments and various particulars of image content.

Account credits are a global currency, which may, but need not, be tied to one or more official government monetary currency value (e.g., N credits per U.S. dollar, etc.) thereby allowing customers to purchase credits for their account(s) using any form of legal payment (e.g., payment obtained and verified electronically via financial institutions, credit organizations, etc.) or direct monetary payments, whether in Dollars, Euros, Yen, etc., with the account manager system 104 being operative to obtain current exchange rate information and make any necessary conversions from a given legal currency payment amount to an account credit amount. Print units, on the other hand, are valued for a given device type and possibly other factors, in terms of units per account credit on a transactional basis at the time of a user request to apply account credits to a particular document processing device, with the valuation being in terms of document processing operations, for instance, one print unit per monochrome page printed by a device 320, 5 print units per printed color page, where a processed ‘page’ as used herein is a single side of a printed media sheet (or a single page of a multi-page document or print job being scanned or operated on by a device 320), such that a device 320 consumes one print unit for printing monochrome images, text, etc., on a single side of an output sheet, consumes 5 print units for printing color images, text, etc. on a single side of a printable medium, and consumes 2 print units to print monochrome images, text, etc. on both sides of a printable media sheet in one example. The application of credits to devices 320, moreover, may be done with respect to integer and/or fractional credits and print units. For example, the customer may specify a given amount of account credits (in whole credits or fractions thereof) to be ‘applied’ to a device 320, and the account manager system may present the customer with the number of converted print units for that device 320, and the device may be adapted to accept fractional print unit amounts or the account management system may perform rounding to provide only integer print unit amounts, with any fractional values being retained as fractional credits in the customer account.

As illustrated in FIG. 3, the account information 110 also includes registered device information 114 with device subaccount information 115 for a plurality of device subaccounts individually associated with a particular document processing device 320 registered by the customer to the account. The device subaccount information 115 for individual device subaccounts includes a device serial number 115 a to identify devices 320 registered to the account, a device mode indicator 115 b (e.g., including a value indicating toner out, a value indicating whether or not the corresponding device 320 is managed by the system 104, etc.), a remaining print unit value 115 c indicating the amount of print units previously applied by the customer to the particular document processing device 320 and currently available to enable the particular document processing device 320 to perform document processing operations, at least one current page price ratio (CPPR) value 115 d indicating the number of applied available print units the particular document processing device 320 will consume to print a color page, a total applied print units value (TAPU) 115 e, and a total print unit used (TPUU) value 115 f indicating the total number of print units used by the corresponding document processing device 320. In addition, the device subaccount information 115 includes registered consumable(s) information 115 g including consumable information 116 for one or more consumable individual components 322 operatively associated with the particular document processing device 320 with a consumable serial number or other identifier 117, and a remaining print units value 118 in one example.

In operation, a customer can request an estimate of remaining pages for a specific device 320 registered to the customer's account via an agent 360 and the portal 102, and the account manager system 104 in one embodiment will provide the remaining print units count value 118 in response. In certain implementations, the customer can use the agent to directly obtain this count value from the device itself via the agent 360 and the customer network 302 (e.g., the device 320 will report the current remaining print units value 323 e from its internal data in memory 323 as shown in FIG. 4). In certain embodiments, the account manager system 104 may provide the customer with an estimate of the number of remaining mono and color pages printable, for example, by analyzing historical print data (color vs. mono printing) for the particular device 320 and use this in conjunction with the CPPR value 115 d to estimate the number of mono and color pages for the customer. The account information 110 can thus accommodate multiple accounts for multiple customers 300, each associated with multiple document processing devices 320 of an unlimited number of different device types, where the devices can have one or more identified consumables 322 for management by the account manager system.

Referring also to FIGS. 4 and 7, an exemplary document processing device 320 is shown in FIG. 4 with a processor-equipped controller 321 and a memory 323, where the device 320 is programmed or provided with suitable processor-executed software, firmware, logic, etc. to controllably provide document processing functions such as printing, faxing, scanning, or combinations thereof and to implement the print unit consumption features of a device registered to an account managed by the account manager system 104. In the illustrated example, a communications interface 326 provides for interfacing the device 320 with the customer network for communicative exchange of data, information, print jobs, etc. with other networked devices, computers, etc., including user computers 330 and agents 360 thereof, and with the account manager system 104 via the portal 102. In addition, the device 320 includes one or more document processing components or systems, such as one or more print engines 325, a scanner 328, media supply 324, and consumable(s) 322, and other such devices (e.g., scanners, sheet feeders, etc., not shown). The memory 323 in this example stores program code and processor-executable instructions for implementing the device functionality, as well as local data to support this operation, including the current device mode information 323 a (e.g., corresponding to the mode information 115 b in the account information 110 in FIG. 3), one or more current page price ratio value(s) (CPPR) 323 b (corresponding to the CPPR value(s) 115 d), a TAPU value 323 d (corresponding to TAPU value 115 e), a TPUU value 323 d (corresponding to TPUU 115 f), and consumable information 323 f obtained from processing elements of the consumable(s) 322 via the controller 321 (corresponding to consumable information 116 in FIG. 3), where the customer agent 360 operates when possible to obtain information from the device 320 (while device 320 is connected to the network 302), and updates the account information of the account manager system 104 accordingly.

FIG. 7 illustrates exemplary operation of the document processing device 320 in a process 400, in which the device 320 is initialized or registered at 402 to one or more customer accounts by the customer 300 or by a reseller 200, and one or more print units are applied to the device 320 by the customer via a customer agent 360. The example of FIG. 7 is illustrated and described in the context of a printing operation, but similar operation is provided for any other form or type of customer/user-requested document processing operation by a device 320. At 404, the device 320 receives a print job from the customer network 302 (alternatively print job may be part of a copy operation initiated at the device 320 itself, or a print job could be provided by a computer 330 connected to the device 320 even if the device 320 is currently not connected to the network 302). At 405, in one embodiment, the device 320 optionally selects an appropriate current page price ratio (CPPR) from a stack 119 (FIG. 6 below) of page price ratio (PPR) values 119 a according to the current value of the total print units used (TPUU) 323 d and according to a threshold value TPUU_(TH) 119 b in the stack 119. At 406, the device 320 in one embodiment determines the cost for performing the job in terms of print units according to the coverage and color content on a page-by-page basis using CPPR value(s) 323 b (FIG. 4), and a determination is made at 408 as to whether the remaining print units (value 323 e in FIG. 4) is less than a threshold. In other implementations, the device 320 may determine the job cost based on color content for the entire job (i.e., page cost determined to be ‘color’ for each page if at least one page of the job uses color).

As shown in FIG. 3, the device subaccount information 115 for individual device subaccounts in certain embodiments may include a plurality of different current page price ratios 115 d indicating the ratio of the number of applied available print units particular document processing device 320 will consume to print a color page vs. that of a monochrome page, which correspond to different page coverage levels for color pages of documents to be processed. Moreover, the device 320 likewise maintains a corresponding plurality of CPPR values 323 b as shown in FIG. 4. In this manner, the account manager system 104 authorizes a specific document processing device 320 to determine page coverage levels for a given color page of a given print job and to consume a corresponding number of available print units to print the given color page according to the corresponding current page price ratio 115 d chosen based on the coverage. The CPPR selection for coverage differences can be done in some embodiments on a page-by-page basis. In other embodiments, the device 320 may be configured to determine an average coverage level for all or a subset of the pages of a given jobs and select the corresponding CPPR 115 d for the entire job. Moreover, the account manager system 104 may provide the devices 320 with multiple pairs of page price ratio (PPR) values 119 a and corresponding threshold values (TPUU_(TH)) 119 b with each pair corresponding to a different page coverage value, as shown in FIGS. 5 and 6. In certain embodiments, CPPR may be applied based on printing over a time period, such as days or weeks, or be based on attainment of cumulative totals for a number of pages or jobs.

Returning to FIG. 7, if the required number of print units is available (NO at 408), the print job is processed by the device 320 at 410, and the process 400 returns to await the next document processing task/job at 404. If, however, the remaining number of print units is below the threshold (YES at 412), the device 320 reports the remaining print units (value 323 e in FIG. 4) to the user (e.g., via an on-board display and/or via a print driver employed in submission of the print job), and reports the remaining print unit value 323 e to an agent 360 via the customer network 302 if currently connected thereto. At 414, the print job is processed by the device 320 (if possible using remaining print units), and the value 323 e is decremented according to the cost of the processed job. Otherwise, a determination is then made at 416 as to whether any print units are left in the device 320 (e.g., whether the value 232 e has reached zero). If the device is depleted (YES at 416), the device 320 notifies the agent 360, which then notifies the account manager system 104 of the empty status of the device 320, and the account manager system 104 may optionally allow the device 320 to perform at a predetermined reduced level of functionality at 418 (e.g., only print monochrome, only print small jobs, only perform faxing and scanning, etc.) according to the reduced functionality information 111 e (FIG. 3). At any point, moreover, authorized customer personnel may apply additional print units to the device at 420 via an agent component 360 and the account manager system 104, after which the unit returns to normal operation. In this manner, the operations of the devices 320 are controlled by the selective application of print units, without which the device 320 will not print (other than the optional account provisions for reduced functionality operation with account-specified restrictions).

FIG. 8 illustrates an exemplary process 500 by which the account management component 106 of the manager system 104 (FIG. 1) adds credits to an account at 510 and applies print units to a device 320 at 520 upon corresponding request(s) from a customer of a specified account via an authorized agent 360 and the portal 102. In the illustrated process 500, the customer and/or agent 360 are notified at 502 that a particular device 320 has no remaining print units (or that the print unit level is below a threshold value, as discussed in FIG. 7 above). At 504, the customer employs the agent 360 to access the device 320 through the customer network 302, and obtains the remaining print unit count (e.g., value 323 e in FIG. 4) from the device 320. At 508, the customer agent 360 accesses the account manager system 104 via the network 10 and the portal 102, updates the corresponding customer account with the remaining print count value (e.g., value 115 c in FIG. 3 above), and obtains the corresponding account information 110 for informing the customer of the current account status, such as currently available credits that can be applied to the empty device, current pricing information, etc.

At 510, the account manager system 104, upon customer credit purchase or ‘buy’ request via the agent 360 and portal 102, selectively adds credits to the specified account at a current rate and add a number corresponding to a paid amount of new credits to the available credits value 111 c for the specified account if and when the payment for such by the customer is verified. In this example, the agent 360 requests the addition at 512 via the portal 102, and arranges payment, such as via an electronic third party payment mechanism, not shown. At 514, when the account manager system 104 is able to verify the customer payment, it adds available credits to the corresponding customer account, and thus increments the value 111 c in the account information 110.

At 520, the account management component 106, upon a request from the customer via the authorized agent 360 and the portal 102, applies print units to a specified document processing device 320 associated with the specified account by converting a number of credits currently available to the specified account into a number of print units according to the specified document processing device 320 and the current pricing information 112 for the specified account at the time of the request. In this example, the customer requests application of print units at 522 to the device using available account credits. At 524, the account manager system 104 converts account credits to print units using the current pricing information 112, and updates the total applied print units (TAPU) value 115 e in the corresponding device subaccount information 115. In one embodiment, account manager system 104 updates a stack 119 (FIG. 5 below) at 525 with a new pair of page price ratio (PPR) and threshold values TPUU_(TH) 119 a and 119 b, respectively, by setting the new TPUU_(TH) to the pervious TAPU value (i.e., the total applied print units (TAPU) value before the current application of further print units). The account manager system 104 sends a message at 526 to the device to add the applied print units (via the agent 360). The device 320 then updates its internal remaining print unit count value 323 e and its total applied print units (TAPU) values at 528. In this regard, it is noted that the valuation of the print unit cost is done at the time of application of print units to devices 320, and not when credits are initially bought by the account holder, whereby the system 104 is operative to track sales transactions at the appropriate time when the customer actually purchases the value of the prospective document processing services, which may include consumable, service, support, and other cost factors.

It is further noted that the interaction of the account management component 106 of the system 104, the agent components 360 on the customer computers 330, and the devices 320 can be implemented using multiple messages for requests, confirmations, authorizations, data exchanges, value updates, and other tasks, and the messages can be created and transmitted via any suitable network protocols, etc., and where the messaging is preferably controlled by appropriate authorization, password permission control, encryption, and other techniques to prevent uncontrolled print unit creation without authorization by the account manager system 104, and to guard against unauthorized access to the account information 110. In an alternative implementation, the concept of print unit deficiency notice may be supplemented or supplanted by an arrangement to use a low or out print unit threshold to trigger an automatic purchase of additional print units.

Referring also to FIGS. 5 and 6, the account manager system 104 and the devices 320 in certain embodiments implement an adaptive form of page price ratio adjustment to accommodate changes in the relative cost of printing color versus monochrome pages for a given device 320. For example, a ratio of three (3) may apply for a given document processing device 320 (e.g., according to the device type, the customer account parameters negotiated with the reseller 200, customer region, etc.) at an initial period of time, and this ratio may thereafter change to two (2). The change in the page price ratio may be a negotiated customer-specific arrangement, such as a discount for color printing in a given year or other time period after a certain threshold number of print units are used by that device (e.g., TPUU value 323 d in the device memory 323, value 115 f in the corresponding device subaccount information 115). In another example, the ratio may change to reflect changes in consumable costs, such as a decrease in color toner cost, with savings passed on to the customer. In order to accommodate such potential changes while minimizing large potential swings in the costs experienced by the customer, the account manager system 104 correlates the ratio with applied print units at the time these are applied to a given device 320, and the device 320 will use the ratio correlated with specific print units as these are expended in performing document processing operations. Thus, for a given device having a large number of print units remaining unused when a page price ratio change occurs, the new ratio will not be applied to the previously applied print units.

To implement this approach, the account manager system 104 and the devices 320 maintain corresponding information stacks 119, where the device subaccount information 115 for a given device 320 in the account manager system 104 includes a stack 119 as shown in FIG. 5, and the device memory 323 also stores a corresponding stack 119 as shown in FIG. 6. As described above and shown at 525 in FIG. 8, each time new print units are applied to a given device 320, the account manager system 104 constructs and sends a message to the device 320 (via the portal 102 and corresponding customer agent 360), including a new stack entry having a page price ratio (PPR) 119 a that is set to the present value of the CPPR 115 d at the time the print units are applied. The account manager system 104 also sets a threshold TPUU_(TH) 119 b in the stack to the previous total applied print units (TAPU) value 115 e of the device subaccount information 115. The system 104 then increases the TAPU value 115 e to reflect the application of new print units for that device 320 and sends one or more messages to the device 320 to provide the stack entry pair PPR 119 a and TPUU_(TH) 119 b to the device 320 and to authorize the increase in the device's remaining pint units value 323 e for the application operation. The device 320, in turn, updates its stack 119 with the new entry pair PPR 119 a and TPUU_(TH) 119 b and increases its remaining print units value 323 e in the memory 323.

During printing or other document processing in this embodiment, (as discussed above and shown at 405 in FIG. 7) the device 320 compares the present value of the total print units used (TPUU) 323 d to the threshold entries 119 b in the stack 119 and sets its current page price ratio (CPPR) value 323 b to the PPR 119 a corresponding to the highest threshold TPUU_(TH) 119 b that is less than or equal to the present TPUU value 323 d in the memory 323. In this manner, the device 320 consumes print units using the page price ratio applicable at the time the expended print units were applied to the device 320, and only uses the next subsequent PPR when the TPUU reaches or exceeds the corresponding threshold TPUU_(TH) 119 b.

Referring also to FIG. 9, the account management component 106 is further operative to update the account information 110 of a customer account via a process 600. In one embodiment, the updating is periodic, such as daily or hourly, although aperiodic updates are possible, such as through customer initiation at any time, and the updates could be initiated based on other criteria, for example, number of prints, credit balance, etc. In practice, the customer agent component 360 can poll devices 320 connected at a given time to the customer network 302 (although the devices 320 need not be connected to the network 302 to perform document processing operations), and to obtain the device account information, and then forward the gathered data, in whole or in part, to the account manager system 104 via the portal 102. At 602 in FIG. 9, an update is initiated by a predefined periodic update time being reached or by initiation from a customer via an agent 360. At 604, the agent 360 obtains current remaining print unit count value information from devices 320 registered to an account, and the agent 360 updates the system 104 with the values and other data via the portal 102 at 606. The account manager system 104 thus receives updated remaining print unit value(s) 115 c for one or more document processing device(s) 320 from a customer via the authorized agent 360 and the portal 102, and updates the registered device information 114 of the account information 110 for the specified account for the document processing device 320.

Referring also to FIG. 10, a process 700 is illustrated for converting previously applied print units to account credits and for transferring print units from one document processing device 320 to another in a customer account. In one implementation, the account management component 106 directly converts print units from a first device 320 to print units for the second device 320 using the current pricing information associated with those two devices 320, generally as a single transaction from the customer's perspective, with the first device's print unit count 323 e, 115 c value being reduced and the second device's value 323 e, 115 c being increased accordingly without modifying the account credit value 111 c. Alternatively, a first transaction is used to transfer print units from the first device and convert these into account credits, and then a second transaction converts account credits and applies print units to the second device, where this form of implementation is illustrated in the embodiment of FIG. 10. At 702, the customer employs an agent 360 to access a first device 320 via the customer network 302 and obtains the remaining print unit count from this device at 704. At 706, the customer uses the agent 360 to transfer print units from the first device 320 to a second device 320 registered to the account. At 708, the agent 360 accesses the account manager system 104 via the portal 102 to initiate the print unit transfer. Any number of devices may be involved in print unit or account credit transfers, as example, from one device split for transfer at some desired ratio to two other devices or credits taken from two devices and applied to a third or to the general account so credits may be later allocated to one or more devices as desired.

At 712, the account manager system 104 converts a number of print units previously applied to the specified first device 320 into a number of account credits available to the specified account according to the specified document processing device 320 and the current pricing information 112 for the specified account at the time of the requested transfer, updating the corresponding available account credits and authorizing the agent 360 to reduce the first device's remaining print unit value 323 e (an also updating the print unit value 115 c in the stored account information 110). At 714, the account manager system 104 applies print units to the specified second device 320 according to the customer request by converting converted account credits into a number of print units for the second device (320) according to the current pricing information (112) for the specified account at the time of the request, and the corresponding values and account data 110 are updated, with the agent 360 being authorized to apply the print units to the second device. At 716, the agent 360 updates the first and second devices 320, and the devices 320 update their internal count values at 718.

Referring also to FIG. 11, an exemplary process 800 is shown for a user to perform printing operations on a public device 320 registered to a vendor account using credits from the user's account via the account management system 104. This process is implemented via the account manager system 104, with the account management component 106 allowing a user at 802 to establish a user account and to add credits to the user account (e.g., 510 in FIG. 8 above) via a user-authorized agent 360 and a portal 102. At 804, a vendor is allowed to register a particular document processing device 320 to a vendor account as a public device 320 via a vendor-authorized agent 360 and the portal 102. The user at 806 connects to the vendor public device 320 via a vendor network. In one situation, the vendor is a print/copy service with a wireless network in their lobby, and with one or more printers, copiers, fax machines, or other document processing devices 320 designated for public use (by registered users) and registered to the vendor's account. A user, such as a business traveler, having a registered user account with the manager system 104 enters the vendor site with a laptop computer, and accesses the vendor's wireless network and discovers one or more printers available to print a job for the user. At 808, the user submits a print job to a selected vendor printer device 320 (a public device), and an agent component 360 on the laptop computer connects to the account manager system 104 via a portal 102 to request usage of the vendor's public device 320.

The account manager system 104 receives the request at 810, and applies available print units at 812 to the public device 320 (associated with the vendor's account) via a vendor-authorized agent 360 operatively coupled with the public device 320, and the manager system 104 converts a number of credits currently available to the user account into a number of print units according to the public device 320 and the current pricing information 112 for the vendor account at the time of the request. The vendor device 320 then prints the user's job at 814, and the account manager system debits the user's account credits at 816 according to the number of print units used by the vendor public device 320, based on the pricing information established in the vendor's account.

The disclosed methods and account manager systems thus facilitate accounting, provisioning, and controlled usage of a variety of different devices 320 associated with an account, allowing pricing for printing, scanning, faxing, support etc. to be tailored according to the type of service or product model, as well as selective inclusion of costs for consumables 322, service, and support according to specific accounts established for different customers, and for different locations or regions, and any other account-specific factors arranged by a manufacturer implementing the account management system 104 and/or by a reseller 200. The architecture, moreover, allows pricing changes to be made easily by simply updating the account credit-to-print unit conversion information (pricing information 112) at the management system data store. The system 104 also facilitates transfers of prepaid print units from one device to another as well as from a device 320 back to a customer account, thereby enhancing a customer's ability to manage printing devices and users. The customer is also able to selectively include various print unit pricing options, including service, consumables, and/or support, which can vary with the device age and the amount of usage within a given time period, thereby providing better adaptability for valued customers. The plan terms and provisions, moreover, are easily altered by changes to the stored account information 110 by agreement with specific customers. The system also allows consumables, such as toner cartridges, to be transferred from one device 320 to another, with the receiving unit reading the consumable identifier (e.g., serial number) and updating the management system account information accordingly. Moreover, the systems and methods disclosed above allow a specific device 320 to operate at predetermined reduced functionality levels if the device print units become depleted, for instance, where the printer is disconnected from the network 302, thereby allowing the customer to maintain operation until more print units can be applied via the account manager system 104.

Referring also to FIGS. 12-16, certain embodiments of the account manager system 104 advantageously provide automated or semiautomatic refunds for customers who return spent consumable products 322 used in or with the document processing devices 320, including without limitation toner, toner or ink cartridges, ink, replaceable fuser modules/components, replaceable imaging units, waste toner bins, transfer belt, or other non-print media items or materials consumed by the device 320 during document processing operations. In conventional return/refund programs, the customer is asked to return empty toner cartridges or other spent consumable items to the manufacturer or reseller 200, and upon receipt thereof, the customer is sent a refund payment or is provided with a coupon usable to purchase further products from the manufacturer/reseller. In practice, however, customers have not consistently complied with such programs. In order for manufacturers or resellers to successfully implement a recycling provision of a consumable product lease arrangement, fuller customer participation is facilitated by the account manager system 104. In this regard, the account manager system 104 is configured in certain embodiments to initiate refunds by automatic addition of credits to the customer account, and in certain cases, to also perform direct application of print units to the specific document processing device 320 from which a returned consumable product 322 came. Thus, while manufacturers and resellers 200 cannot realistically force customers to return consumables 322 designated as part of a recycling provision of a product lease or consumable purchase program, the automated refund aspects of the account manager system 104 can provide an effective incentive for customer compliance beyond that possible in conventional programs. The system 104 thus facilitates materials reclaim and socially responsible expended item disposal or recycling for consumables 322 provided as part of the prepaid program as well as for externally sourced consumables.

One exemplary process 900 is shown in FIG. 12, in which the account manager system 104 automatically adds account credits and if possible, applies device print units as a credit or refund incentive for a returned and/or newly installed consumable product 322. At 910, the account manager system 104 verifies that a replacement consumable 322 has been installed into, or that a replaced consumable 322 has been returned from, a document processing device 320 registered to a customer account. The account manager system may verify the association of an installed/returned consumable 322 with a particular customer account by any suitable means or techniques, and various techniques may be used to potentially associate a returned consumable 322 with a particular document processing device 320, several of which are illustrated and described in greater detail in connection with FIGS. 13-16.

If the identity of the source device 320 (device ID) is known (YES at 912), the account manager system 104 is programmed to automatically add account credits to the associated customer account at 920 (e.g., increasing the available credits value 111 c in the account information 110 for that customer account in FIG. 3), and to automatically apply print units at 930 to the identified document processing device 320 (an apply operation similar to that described at 524-528 in FIG. 8 above, without requiring customer action). In certain embodiments, the return refund can be performed as a single operation to apply a full or partial refund amount directly as applied print units without first adding account credits.

In the example shown in FIG. 12, the account manager system 104 converts account credits (e.g., those added at 920) to print units at 932 using the current pricing information 112 (FIG. 3), and updates the total applied print units (TAPU) value 115 e in the corresponding device subaccount information 115. In one embodiment, account manager system 104 updates the stack 119 at 933 with a new pair of page price ratio (PPR) and threshold values TPUU_(TH) 119 a and 119 b, respectively, (FIG. 5) by setting the new TPUU_(TH) to the pervious TAPU value (i.e., the total applied print units (TAPU) value before the current application of further print units). At 934, the account manager system 104 sends a message to the device 320 to add the applied print units (via the agent 360). At 936, the device 320 updates its internal remaining print unit count value 323 e (FIG. 4) and its total applied print units (TAPU). As in the user-requested print unit application described above, the valuation of the print unit cost is done at the time of application of print units to the device 320, and the system 104 tracks the refund transaction. In certain embodiment, moreover, the account manager system 104 sends an email at 937 to notify the customer of the application of print units to the particular document processing device 320.

In situations where the customer identity is known, but the source device 320 is unknown (NO at 912), the account manager system 104 can be configured to either add account credits and notify the customer or to notify the customer and provide a means for the customer to initiate addition of account credits for the refund amount. In one example (940 and 942 in FIG. 12), the account manager system 104 automatically adds the refund amount of account credits to the associated customer account at 940 by increasing the available credits value 111 c in the account information 110 (FIG. 3), and may send an email to the customer at 942 with a notification that credits have been added. In this regard, the emails sent to the customer at 937 and 942 preferably include an indication of the type of consumable 322 that was returned and the amount of credits applied (as well as the identity of the device 320 to which print units were added at 937) in order to provide timely information that will encourage/reinforce the customer's actions in returning used consumable products 322 to the manufacturer/reseller.

In another example (946 and 948 in FIG. 12), if the customer identity is known but the specific source device 320 is unknown (NO at 912), the account manager system 104 sends an email to the customer indicating that the returned consumable 322 has been received (and/or a new consumable 322 has been installed), and providing a promotion code for a given amount of account credits. The email may provide a website link or instructions for the customer to access the account manager system 104 (e.g., via an agent 360 on a customer computer 330 and the portal 102 in FIGS. 1 and 2 above), and the customer then uses the agent 360 at 948 to initiate addition by the account manager system 104 of the refund amount of account credits by entering the promotion code. As noted in the process 900 of FIG. 2, the account manager system 104 may be configured to initiate one or more automatic or semi-automatic consumable refund actions, such as adding account credits, applying print units, etc., at various times, including without limitation when a replacement consumable 322 is installed into a device 320, when the consumable 322 is received at a return center, or both. For example, in one implementation, a partial refund may be provided when the product 322 is initially installed, and the remainder of the refund may be provided when the spent consumable 322 is returned.

Referring also to FIG. 13, the consumable product 322 in some instances may include onboard electronics with readable and/or writable memory, such as a customer replaceable unit monitoring (CRUM) memory, to facilitate determination by the account manager system 104 of an association between a specific device 320 and a returned/installed consumable 322. FIG. 13 shows a process 950 in which a customer installs a consumable product 322 into a document processing device 320 at 951. At 952, the device 320 reads a consumable identity (e.g., serial number or other identifying information) from the CRUM memory of the installed consumable product 322 (e.g., upon initial consumable installation or anytime thereafter). Alternatively, such information can be entered into the device 320 by the customer via a device user interface or via agent application 360 on a customer computer 330 (FIG. 1 above). The device 320 may store the consumable identity (ID) in its internal memory at 952 as consumable information 323 f (FIG. 4). At 953, the device 320 forwards the consumable ID to the account manager system 104 for storage in the account information 110 (via an agent 360 and the portal 102), and the account manager 104 stores the consumable ID 117 in the corresponding device subaccount information (FIG. 3) at 954. At this point, the account manager system 104 has an established association between a specific document processing device 320 and a specific consumable product 322 via the account information 110. At some point in time, the customer returns the consumable 322 at 955 to the manufacturer or a reseller 200. At the return center, the consumable identity is read at 956, and the return center (e.g., the manufacturer or reseller 200 or other return site having network access to the account manager system 104) updates the account manager system 104 with the identity of the received consumable product 322. At 957, the account manager 104 uses the received consumable ID to index the account information to ascertain the identity of the associated device 320 and initiates one or more automatic refund actions as outlined above (e.g., adding account credits and possible applying print units).

Referring to the process 960 in FIG. 14, in another implementation, the consumable product 322 includes a writable memory and the device 320 into which the consumable is installed at 961 writes its identity (the device's identity) into the consumable memory (CRUM) at 962 for use in initiating automatic refund actions when the consumable is returned or at installation or both. In one implementation of this scenario, when the account manager system 104 determines that a consumable level is low for a given device 320 (e.g., through monitoring of the TPUU values 115 f in FIG. 3), a replacement consumable product 322 is shipped to the customer, for example, along with a return envelope for the used consumable for return shipment. Once the consumable 322 is returned to a recycling center at 963, the CRUM data can be scanned and the serial number (identity) of the received consumable product 322 is sent to the account manager system 104 at 964. At 965, the account manager system 104 initiates one or more automatic refund actions based on the identified source device 320 and the known consumable identity.

Referring now to FIG. 15, the account manager system 104 may employ the account information 110 (FIG. 3) in a process 970 for initiating refund actions for consumable products 322 that do not include onboard electronic memories. In this regard, serial numbers or other identity information can be tracked by the system 104 along with other customer registration information so that the automatic or semiautomatic refund credit process may be applied to recycle items that have a serial number but do not include a CRUM or other means of positive correlation to the document processing device 320 that the consumable 322 was associated with. Serial number information of such recycled consumables 322 can be linked in the system 104 to the device 320 for which they were initially sent to be used such that when a customer returns the consumable 322, credit is provided to the corresponding customer account.

At 971 in FIG. 15, the account manager system 104 monitors one or more consumable levels (e.g., toner level(s)) for one or more devices 320 registered to an account, such as through reports forwarded from the monitored devices 320 and corresponding updates to the account information 110. For example, the devices 320 report updates to the TPUU (total print units used) value that are stored as values 115 f in the device subaccount information 115 for the devices 320 (FIG. 3). The account manager system 104 can track these values, in conjunction with knowledge or estimation of the TPUU value at which a particular consumable 322 was installed in the device 320 and known capacity values of the consumable 322 (e.g., number of print units possible per consumable product 322), and determine when a particular document processing device 320 needs or will soon need a replacement consumable 322. At 972, the account manager system 104 automatically initiates shipment of replacement consumables 322 based on monitored consumable levels to the customer for a particular device 320 (with or without corresponding email or other notice of shipment). The replacement consumable 322 is shipped in certain embodiments along with a return label, carton, and/or promotion code identifying the consumable/device association. At the time of the shipment, in one embodiment, the account manager system 104 automatically performs one or more automatic refund actions at 973 for all or a portion of the refund value, which can be addition of account credits and possibly automatic application of print units as discussed above. At some point, the customer returns the replaced consumable product 322 at 974. When the consumable 322 is received at a return center at 975, the identity of the source device 320 is read from the return label, carton and/or from the promotion code, and the account manager system 104 is updated (e.g., via the portal 102) with the device identity information. At 976, the account manager system 104 uses the customer account and source device identity information to initiate one or more automatic refund actions.

FIG. 16 illustrates another exemplary process 980 in which the account manager initiates automatic consumable replacement actions based on inferred association of returned consumable 322 with a document processing device 320 identified based on total print units used TPUU information 115 f of the account information 110 (FIG. 3). At 981 in FIG. 16, the customer returns a consumable product 322, and the return center updates the account manager system 104 at 982 with the returned consumable type and customer information from the corresponding shipping information. Knowing the customer identity, the account manager system 104 infers the identity of the source document processing device 320 at 983 from which the consumable 322 was returned based at least partially on tracking of the TPUU information 115 f (FIG. 3) for one or more devices 320 registered to the customer's account. For example, if it is known that the returned consumable device has a print unit capacity of X print units, the account manager system 104 can ascertain from the account information 110 the registered device subaccount(s) 115 for which the TPUU has changed by X units since shipment of a previous replacement consumable of the same type to infer the source device identity. Using this inference, the account manager system initiates one or more automatic refund actions, including adding credits to the corresponding customer account, and optionally sending a notification email to the customer and/or applying print units to the presumed source device 320.

The automatic or semi-automatic provision of account credits and/or print unit application for returned consumables 322 advantageously encourages customer participation in consumable return/recycling programs since customers readily see the benefit for return compliance in their account credit and/or print unit balance, particularly when the account manager system 104 provides a timely email notification. Moreover, these techniques provide lower administration costs for the manufacturer/reseller 200 compared with conventional monetary compensation or coupon programs for returned consumable products, since a customer account already exists that can simply be credited by an amount determined by contractual return/refund provisions and/or as modified by special enhanced refund offers (e.g., limited-time, customer-specific, region-specific, or other special offers, etc.). From the customer's perspective, participation is encouraged by lower operation costs associated with the office equipment and the customer can track their recycle participation by device 320 and/or department 310.
